Just days after a Brazilian woman who may or may not have been a prostitute videotaped him sleeping soundly in a bed, Justin Bieber found himself hungry for something else entirely!!!

The Boyfriend singer, who is now in Argentina, apparently took his mom Pattie Mallette, and their entourage out to eat at Sushi Club in Buenos Aires last night!

Awww!!! So cute!! We're sure she was thrilled to spend QT with her baby boy!!

We wondered if they ordered any eda-mommy! Ha! We slay us!

The restaurant's assistant manager in fact dished on all of the glorious seaweed-wrapped deets about Justin's meal, revealing:

"[Justin] was with his family having a nice dinner. They had a variety of sushi. They were having a good time and they were relaxed. They had a table in the back and it was busy but they enjoyed their dinner and seemed happy and having a good time."

Nice! We bet a quiet dinner is just what the doctor ordered after a controversial Brazilian trip which wound up getting spicier than a mouthful of wasabi!

Though the Biebs is technically old enough to wet his whistle in Argentina, it's looking like he abstained!

The source continued:

"They came in around 1:30 p.m. It was his mom, two little kids, and a younger guy in his 30s and a lady that didn't seem to be family—she was working and organizing things. They had a shrimp appetizer and then had crispy prawns, sushi rolls, an avocado roll and sashimi including salmon, whitefish, and tuna… They drank water except for the guy in his 30's who had a beer. They were all very friendly and were very nice people."

Mmm, sounds YUMMY!

We scoured the restaurant's online menu for prostitutes, but, sadly for the Biebs, this establishment only deals in fresh fish!

But, hey, a tiger roll for $87 Argentinian pesos? Who can argue with those prices?

oh god. I can vomit already. I've dated japanese females (and to a lesser degree, other types of asians) for most of my adult life so far and love everything about japanese culture BUT their raw fish and raw meats. My girl's father use to take me out for sushi/sashimi all the time but I finally had to set him straight because I got tired of torturing myself trying not to offend him by insulting japanese food. "sorry, I come from a 'cooked meat' culture. To some cultures.. eating termites is cool, but you would have a hard time with that because its not your culture". "no problem! I'm offended that you didnt tell me that sooner. You should be comfortable enough with me by now to say what you are thinking. You've known me for years now. we'll go eat hamburger next time!" wheeeeew. Not rare burgers either.
